Thiomorpholine 1,1-dioxide, A common heterocyclic compound, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route., 39093-93-1
3′,5′-O-(Tetraisopropyldisiloxane-1,3-diyl)-2′-O-(1,1-dioxo-1lambda6-thiomorpholine-4-carbothioate)-uridine (8.9 g, 15 mmol) was dissolved in Me-THF (75 mL, 0.2 M) and thiomorpholine-1,1-dioxide (2.23 g, 16.5 mmol) was added. Reaction mixture was stirred for 2 h at ambient temperature. Hydrogen fluoride pyridine (HFxPy) (2.33 mL, 90 mmol) and pyridine (5.05 mL, 63 mmol) were added drop-wise. Reaction mixture might be cooled if warmed up. The mixture was stirred for 2.5 h at ambient temperature. The reaction mixture was extracted with water (75 mL). The aqueous phase was extracted with Me-THF (2.x.150 mL), organics were combined and dried (100 g Na2SO4), filtered and evaporated. Yield 6.3 g (100percent). Rf (TLC 10percent MeOH/DCM): 0.25., 39093-93-1
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. 39093-93-1. We look forward to the emergence of more reaction modes in the future.
